Nec Code For Grounding Rods at Pauline Smith blog

Nec Code For Grounding Rods. installing grounding electrodes (in particular, rods) 6 feet apart because that is the minimum separation required by code. learn about the different types and lengths of grounding rods allowed by the nec for electrical installations. section 250.52 provides a list of what items can be used as a grounding electrode. Metal underground water pipes under certain conditions; according to nec 250.56, the recommended grounding resistance should be less than 25 ohms, and for sensitive applications like icu units in hospitals, a maximum resistance of 50 ohms is allowed. 250.53 (a) (4) for installation requirements of rod or pipe electrodes. Each ground rod has its own zone of influence as shown in figure 2. refer to sec. when grounding or bonding, or performing any electrical work governed by the nec, remember the purpose of the code: The upper end of the rod is to be flush with or below ground level unless.
